Abstract (en)
[origin: WO2004113690A1] The present invention relates to a converter device adapted to being arranged in an exhaust system of a combustion engine. The converter device comprises an outer casing (1), a tubular body (4) enclosed by said casing (1), and a passage for leading exhaust gases through the converter device. In order to provide good sonic damping properties, the converter device needs to comprise a long passage for exhaust gases. In order to provide a compact converter device with a long passage, the converter device comprises at least one axial exhaust duct (13 a, b) which has a helical extent round the tubular body (4), and a radial exhaust duct (13 c, d) which has a spiral extent between a first portion (17a) of the passage, which is situated external to the tubular body (4), and a second portion (17b) of the passage, which is situated internally to the tubular body (4).
